High DPI Windows app usage

With a growing number of high end laptops carrying high resolutions (such as Dell's 3200 x 1800 XPS 15 and Precision machines), I've noticed many reviews saying how nice these are apart from Windows' mixed performance at making applications useable. That strikes me as a bit more important than a side issue, so I'm wondering what the experience is really like.

Is there anyone here who has one of these and would be kind enough to post some full screenshots we could view to get a sense of scale of how small the buttons and menus are in applications which haven't yet had a specific "high dpi" upgrade to address this directly? I'm particularly interested in creative tools like Adobe CS5, which I'd like to hold onto but aren't likely to be high dpi-enabled without switching to CS6 or CC versions.

For starters and comparison purposes, I've simulated a 3200 x 1800 Premiere Pro CS5 screen by taking a full screenshot from my 1920 x 1080 machine and scaling it. Looking at the result full screen (not as nice as the high DPI screen would be, obviously, but just to get used to how small the elements might be) it looks pretty hard to get used to. But if this is your experience with a new machine, how are you getting on?
